4 Claims.

My present invention relates to portable ventilating attachments for radiators.

More particularly, my invention is directed to a portable ventilating attachment, preferably de-' signed for association with the frame opening of a window or the like of a building or the like, and with any conventional or other approved thermal radiator, serving a room or other space of such building, to provide at the option of the user fresh air, 1. e., air of the atmosphere outside of such building, and/or air of such space re-clrculated. Heating or cooling of such fresh air and/or recirculated air, in variant relative proportions and variant total quantity may be accomplished as desired.

structurally, embodiments of my invention comprise each a casing having an air ingress opening leading to the outer atmosphere; a regulatable air ingress opening for the inflow of air of the room; air outflow means having two outflow discharges, regulatable in respective relative 'proportions, leading, respectively, directly into the interior of the room and in thermal exchange relation to the thermal surfaces of a radiator or equivalent; and air projecting means for positively, and at regulatable rate of effective flow, inducting fresh air and/or re-circulating room air and projecting the same into the interior of the room in desired proportions of thermally and non-thermally treated air. Further features and objects of my invention will be more fully understood from the following detail description and accompanying drawing, in which- Fig. 1 is afront elevational view illustrating a manner of practical application of an embodiment of my invention, installed in a window opening of a building, in association with a radiator of conventional type serving a room of such buildin Fig. 2 is a transverse vertical sectional view of a preferred type of embodiment of my invention installed and associated as illustrated in Fig, 1, and shown in an enlarged scale;

Fig. 3 is a detail sectional view taken on line 3--3 of Fig. 2.

Referring to the preferred embodiment illustrated in the drawing, such embodiment of my invention, indicated generally by the reference number in, is shown constructed and arranged to be installed in the opening I I of a window and in association with a radiator or other suitable thermal appliance. Certain preferred types of embodiments of my invention are designed for association with a radiator l2, of conventional type,

such as is indicated in Fig. 1, which may be supplied in such instance with steam, hot water or other appropriate heating medium.

The illustrated embodiment of my invention comprises, a casing l3, generally of attachable and freely portable cabinet form, and provided at one side, see side l3a, with an opening, designated generally I 4, for the ingress of air derived from the outer atmosphere; saidcasing being provided further with air ingress means, designated generally i 5, for the inflow of air of the room for circulation and re-circulation; suitable air inducting and projecting means such as a fan, or equivalent, indicated generally at i6, for positively inducting air through the stated fresh-air ingress opening it and/or the stated air ingress means l5, and outlet means communicatingwith the discharge of such air inducting and projecting means [6, for projecting air either in thermal exchange relation with the thermal surfaces of any suitable type of radiator or other thermal applianc'e and/or directly into the interior of the room, provision of means being had for regulating the respective inducted air flows and respective thermally and non-thermally treated projected air streams.

The stated attachable and freely portable cabinet types of embodiments of my invention, as will appear, possess the advantages of simplicity of construction, attendant low cost of assembly, ease of installation, ease of removal, simplicity of operation and setting of regulatable parts, etc.

Commercial embodiments of my invention may be produced of variant sizes and capacities; one type being that indicated in the drawing, namely dimensioned for a particular width of frame opening of a window or the like; however, the dimensions and capacity of commercial embodiments may be standardized, say, in restricted number of sizes, and auxiliary devices such as plates of variant sizes or adjustable plates, disposed laterally of the cabinet to completely fill the frame opening.

As indicated, in Figs. 1 and 2, it is convenient in the use of cabinet types of embodiments of my invention to install the same in a window opening by raising the lower sash of such window, indi cated at Ila, sufllciently to receive such cabinet and upon lowering such lower sash l I a to engage the upper wall of the cabinet I 3, thus securely retaining my cabinet in position and restricting the influx of the outer air solely through and under control of my cabinet.

The fans or other air inducting and projecting means 5 may be of any suitable type. As illustrated in the drawing, see particularly Fig. 3, there may be provided a pair of the fans, l6, [6, the shafts of which are respectively directly connected, on opposing sides, with the shaft of a suitable motor l1, desirably an electric motor, 'regulatable by a switch indicated at I'Ia, for on, off and intermediate speeds, and operated either manually or automatically for temperature and/or humidity control. The discharge channels of the respective fans I6 are indicated at I 612. Such fans I6 may be of the squirreltype, to afford freedom of air movement therethrough during the period of non-operation.

Advantageously, the air ingress opening I4 isprovided with a set of mutually spaced bafiles l4a, extending horizontally and inclined upwardly in the direction of air flow to provide for the paths of fiow of the outer atmospheric air indicated by the applied arrows.

The inner walls of such air ingress opening l4 may be lined with sound absorbing material, if preferred. Desirably, a filter l8, for removing dust, noxious fumes, etc., and also reducing the "noise level, may be employed, such filter being preferably, as shown, interposed in the path of air fiow through the air projecting means IS.

The discharge of the outer air and/or recirculated air in regulated relative proportions, is effected, as desired, either directly into the room or other space served by the radiator or in thermal exchange relation with the thermal surfaces of a radiator or other thermal unit, or both in desired regulated proportions. To such or like purposes, the cabinet includes a compartment l9 provided with louvre elements 20, preferably regulatable, as by pivoting the same and I interconnecting by means of a link 2| settable by a manually or other operated lever 22, the compartment 19 communicating with the discharges lGa of the fan compartments through the opening 23 controlled by a valve 24, shown,

hinged at 24a and operated to desired set position by any suitable means, such as a knurled head 25. Discharge of the air delivered by the one or more fans [6 in thermal exchange relation with a radiator such as is conventionally illustrated at 12, is afforded by a depending conduit portion of the casing 26 communicating through the opening 23 with the fan compartments l6, and regulated by the valve 24.

Desirably, the casing 26 is dimensioned to extend, when positioned within a window opening, as is indicated in Figs. 1 and 2, in close adjacency relative to the uppermost areas of the thermal surfaces of such radiator l2, to afford effective cooperative substantially coextensive relation with such upper surfaces by snugly enclosing relationship, and to further afford ready disassociation with the radiator by mere grasping and removal in upward. direction of the cabinet as a whole.

The control of the desired proportion of relines'of the valves I5 and 24, shown in Fig. 2, indicate the range of movements of the same, as will be understood.

The relative parts of the casing I3 and the assembly of the same are desirably designed for simplicity of individual formation, usually of metal, and for affording removal of dust, access to the filter, access to the motors, fans, for inspection, oiling and other attention, replacement, etc. As shown, the upper and front sides of the compartment I9 are snapped in position, and are made correspondingly removable by means of suitable spring means, operated by the button 26. Access to the filter l8 and to the motor I! and/or fans I 6, is afforded by a friction joint indicated at I 3b. Access to the compartment I4, open to the outer atmosphere, is afforded by removing" the casing from the frame opening.

Whereas I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made'without departing from the spirit of the invention.
